Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive testing, in particular to a scanning frame structure and a probe adjusting seat. Background Technique

[0002] Ultrasonic testing belongs to one of the nondestructive testing methods. Essentially, ultrasonic testing utilizes the interaction between ultrasonic waves and substances: reflection, refraction, and diffraction. The pulsed wave generated by the sound source enters the workpiece, and the ultrasonic waves propagate forward in the workpiece in a certain direction and at a certain speed. When encountering an interface with different acoustic impedances on both sides (the difference in acoustic impedance is often caused by a certain discontinuity in the material, such as cracks, pores, slag inclusions, etc.), part of the sound waves are reflected, and the detection device receives and displays: analyzes information such as the amplitude and position of the sound waves, and evaluates whether there are defects or the size and position of the existing defects. By evaluating and interpreting these defects, ultrasonic flaw detection is achieved.

[0003] The utility model patent with the application number: CN202022749698.0 and the publication number: CN214201283U (hereinafter referred to as "Prior Art 1") discloses a plate ultrasonic testing leveling device, which includes a base. On both sides of the top of the base, a left convex platform and a right convex platform are sequentially fixed. On the top of the left convex platform and the top of the right convex platform, sliding grooves are respectively opened. On one side of the two sliding grooves inside the left convex platform and the right convex platform, two transverse grooves are respectively opened. Inside the two sliding grooves, a support group I and a support group II are sequentially slidably connected. The support group I and the support group II include two U-shaped supports, four screws, and four rotating blocks. On both sides of the top of the two U-shaped supports, two longitudinal threaded through holes I and two longitudinal threaded through holes II are sequentially opened.

The fixing component is used to fix the probe 101, and the angle adjusting component is used to level the angle of the probe 101. The probe 101 is connected to an ultrasonic detector through a data cable;

[0027] Among them, the fixing component includes a first fixing seat 102, a second fixing seat 103 and a third fixing seat 104.

Threaded holes 111 and relief holes 106 are provided on both the second fixing seat 103 and the third fixing seat 104. The diameter of the relief hole 106 is larger than the diameter of the probe 101. The first bolt 108 is threadedly installed inside the threaded hole 111 on the second fixing seat 103 and is used to contact the end face of the first fixing seat 102. The second bolt 109 is threadedly installed inside the threaded hole 111 on the third fixing seat 104 and is used to contact the end face of the second fixing seat 103. The limit screw 107 is provided on three sides of both the first fixing seat 102 and the third fixing seat 104. Both ends of the tension spring 110 are respectively installed on two limit screws 107 on the same side of the first fixing seat 102 and the third fixing seat 104;

[0029] The utility model mainly includes a fixing component and an angle adjusting component. The fixing component is used to fix the probe 101, and the angle adjusting component is used to level the angle of the probe 101. The probe 101 is connected to an ultrasonic detector through a data cable; during the actual use process, the staff needs to install the whole fixing component on the mounting plate 105, and then install the probe 101 on the fixing component. After installation, it is necessary to level the probe 101. In this process, the staff turns the first bolt 108. After the first bolt 108 rotates, it drives the second fixing seat 103 to rise. At this time, the second fixing seat 103 and the third fixing seat 104 are of an integral structure. Since a plurality of tension springs 110 are arranged between the third fixing seat 104 and the first fixing seat 102, when the second fixing seat 103 and the third fixing seat 104 rise, the tension springs 110 will pull the integral structure formed by the second fixing seat 103 and the third fixing seat 104 to be hinged with the first fixing seat 102, thereby realizing the adjustment of the lateral angle of the probe 101; after adjusting the lateral angle of the probe 101, the staff turns the second bolt 109. At this time, the first fixing seat 102 and the second fixing seat 103 are of an integral structure, and the third fixing seat 104 is hinged with the integral structure formed by the first fixing seat 102 and the second fixing seat 103, thereby completing the adjustment of the longitudinal position angle of the probe 101.
